This application is a non-provisional application of provisional patent application No. 62/132,816, filed on Mar. 13, 2015, and priority is claimed thereto.

FIELD OF THE PRESENT INVENTION

The present invention relates generally pet litter housings and pet shelters, and more specifically relates to a window mounted housing and litter box for use by pets.

BACKGROUND OF THE PRESENT INVENTION

It is known that indoor animals such as cats, ferrets, chinchillas, dogs, and other small pets are prone to employ a litter box filled with pet litter after being trained to use them to use the bathroom. In such scenarios, at least one litter box is conventionally located on the floor in a user-selected location within the home or other structure. Unfortunately, once the litter box has become soiled, there is little the homeowner can do to prevent the creation of odor.

While odor-eliminating sprays can be helpful to temporarily curve the odor, the smell will inevitably return as the pet subsequently uses the litter box. A variety of litter box housings have been invented

Numerous other types of pet litter housings and shelters have been invented in the past. One problem encountered with these designs is that the owner generally does not have access to the housing from the inside of the dwelling. For example, in U.S. Pat. No. 5,165,366, granted to Harvey, one can access the litter box for emptying from outside of the housing, on the ground floor only. Another problem is that the litter housings and shelters have to be mounted on the exterior of the dwelling, which makes installation impossible, unless the dwelling is on the ground floor.

In contrast, the pet housing of the present invention may fit into any window, vertical or horizontal as well, but is installed from the inside of the dwelling and can be done from any floor, from the ground floor to high rise buildings. Furthermore, the present invention differs from Harvey's design, in which the litter tray may only be emptied from the exterior of the dwelling. With the present invention, one may access the litter box from the inside of the dwelling, through the unique triple-door design.

Another comparison is choice of materials. Harvey constructs the entire pet litter housing out of acrylic and metal, not realizing just how hot this will make the inside of the housing in the summer. There is practically no shade on the inside of the box, except for the tin roof This is yet another flaw of Harvey as well, as this too acts as even more of a heat conducting material. This is like putting a cat in a sauna or under a magnifying glass, which is obviously not conducive to the health of the cat, and may even discourage the cat from using the housing. Continuing on, Harvey places many open holes to be used for ventilation. This is conducive to air circulation, but when its very cold out, or raining, those two elements could enter the pet litter housing. Rain can cause the pet litter to become prematurely soiled. Combine this with a completely open floor, and there is basically no protection from the elements.

Similarly, U.S. Pat. No. 5,842,438 granted to Messmer is for a window mounted litterbox. Messmer varies from the present invention in that the landing taught by Messmer is far too small to adequately function as a comfortable access point for a pet. This is in contrast to the present invention, which is equipped with a larger, more ample landing to facilitate access to the housing by a pet.

Additionally, U.S. Pat. No. 7,530,331 granted to Malachowski on May 12, 2009 is for a window-mounted litter enclosure having interior and exterior housing sections. Malachowski is similar to the present invention in that it window mounted, however Malachowski teaches a housing that can only be accessed for cleaning from the outside. Additionally, Malachowski extends within the dwelling, and therefore is not space-saving, unlike the present invention.

In addition, none of the other described inventions, or any product of similar design to the present invention exist in either past or present markets. The main idea behind the present invention is to be marketed to the general public for purposes of improving the quality of life. For example, if someone lives in a tiny or relatively small dwelling, space is of the utmost importance. This is relevant to housing in cities and places like New York City, Europe, Russia, Asian countries, and any other situations where housing is often small, cramped, and compacted. It is known that most of the housing in cities exist in mid-rise and high-rise dwellings.

The present invention is made entirely of high density plastic, with only an acrylic material for the rear window. This allows adequate shade, and does not allow the elements to enter the housing. The side louver vents allow air to ventilate the entire box, but due to their downward slope, allow rain to drip off, but not enter the box. Harvey's patent is similar to the present invention only in the essence of its use, however, it contains all of the flaws mentioned above.

The present invention not only provides a space saving alternative, but also eliminates the odor problems that occur from pet litter housings being in a confined space, with or without adequate ventilation and windows. Additionally, the housings can be provided in different colors, thereby not only saving space, and eliminating odors, but also adding or blending into the existing decor of any dwelling. As such, it should be understood that the present invention is space-saving, odorless, safe, and effectively contains litter spread. The present invention is also preferably ADA compliant.

Another feature of the present invention is to serve as a cat haven and resting place. Due to the width of the housing, enough room is allocated to give an extra ten inches of space inside the housing to be used as a resting place for the pet. The present invention may also be used as a window perch by simply removing the litter pan, left front door, and right front door. The vertical design of the present invention adds a shelf above the litter pan for the same purpose, and is the entire width of the housing. The rear of the housing is preferably equipped with a clear plastic window allowing sunlight to enter and warm the housing, in addition to allowing the cat the ability to view the outside. This again incorporates new features, as well as all the features that other inventions have done individually.

Attempts have been made to provide an adequate swinging door for access, but none compares with the triple-door design of the present invention that not only allows the cat access into the housing, but also to the owner to facilitate litter changing and cleaning. The vertical design utilizes a double-door design that works in the same way. This allows the owner to have 100% access to the litter tray in a normal standing position. Great for anyone who has back problems, unable to bend or stoop over, and any other related problems due to poor health. This also includes anyone confined to an ADA compliant wheelchair, to have full and easy access to the interior of the housing. Therefore the present invention contains many facets within its' design related to improving the quality of life.

Another advantage to the present invention's design is that of safety, in many aspects. No longer is the housing sitting on the floor, where someone could trip over it. Also, with the housing design of the present invention, it can fit inside of a housing designed set of burglar bars, as would a normal window air conditioning unit that is installed on the ground floor or above. Therefore, these are all primary reasons why the present invention is the provision for a new and improved pet litter housing and shelter.

Thus, there is a need for a window-mounted pet housing apparatus configured for installation from within a dwelling, rather than solely from the outside, that has adequate ventilation while protecting from the elements during rain and winter.

SUMMARY OF THE PRESENT INVENTION

The present invention is a four-sided shelter equipped with two solid walls, a rear window made of a transparent material within a frame, and a combination of a triple-door design that comprises the fourth and front wall. The front wall consists f one top (horizontally) hinged swinging flap door, mounted and centered inside a left front door equipped with hinges disposed vertically along the left side of the left front door. The left front door and the right front door that awing out from the housing, providing access to the litter pan inside for cleaning. The flap door allows the cat to enter and leave the housing as it pleases.

A second embodiment of the present invention exhibits a vertical housing that also utilizes a double-door design that is narrower than the horizontal embodiment due to the narrow design of the vertical window. it consists of one top (horizontally) hinged swinging flap door, mounted and centered inside of another (horizontally) hinged door that opens up inside the top of the housing. This allows 100% access to the litter pan inside. The entire housing mounts securely into any standard horizontal or vertical window, with only a few screws. The extension panels seal the rest of the window up in both the horizontal and vertical applications.

The present invention is made entirely of high density plastic, with only an acrylic material for the rear window. This allows adequate shade, and does not allow the elements to enter the housing. The side louver vents allow air to ventilate the entire box, but due to their downward slope, allow rain to drip off, but not enter the box, unlike the prior art. The top of the housing of the present invention is preferably sloped to allow rain to drip off easily.
